I know, not the best title, but I was struggling to come up with something that would fit within the character limit.
My original query was "dynamodb gsi with all ony returning partial data" ("ony", instead of "only"). Performing the same query without the typo however is actually missing the highlighted page and the results are order differently as well.

Links to the search results:

https://kagi.com/search?q=dynamodb+gsi+with+all+only+returning+partial+data&r=us&sh=9PA_zuI6oaiT1aExgnAApg
This isn't a new bug, and the results for the provided example aren't drastically different, but I've had other searches in the past where the query with the automatically corrected typo included better, more relevant results than the same query without the typo.
I'm not sure if the description for "Showing results for dynamodb gsi with all only returning partial data" is actually incorrect, but either way, it doesn't really make sense that there would be any difference, never mind complete pages missing without the typo.
And looking at the shared links in a private tab it might be related to the customizations, though even here at least the results order is also completely different.
